Particular attention is paid to the security systems installed in public utility facilities, including fire protection systems used in urban subway objects (with Warsaw subway as an example). Structure of the integrating system is described and an overview is made of the specialised components used in its design and implementation. Requirements are also presented for obtaining technical approval. Experience gained during the design, implementation and testing of the integrated security system is also summarized.
